.... to make these products fully acceptable and EMC compliant is to limit their usage to cabling that is inherently balanced. In other words, NOT mains wiring, which has none of the characteristics of properly designed network cabling.
Powerline networks is a very bad idea ! The reason is that the data stream is sendt between the PLC units on unshielded mains wiring. Unshielded mains wiring are not designed for frequencies between 2 and 30 MHz (which HomePlug units uses). HomePlug units interfere and "breaks down" licensed radio communications and blocks wireless devices like computer keyboards etc.
EMC-tests has shown that HomePlug units does not meet EN55022 standard, and as such they will be removed from your property if they interfere with nearby radio communications and radio receivers. Huge warnings against this poweline technology have been stated, take a look at what EMC-experts is writing about it:

Ofcom in the UK are also about to be taken to court by the RSGB for allowing this kind of disturbing technology to be sold legally:

My advice is to use CAT-5 wiring or Wifi 2.4 GHz or 5 GHz in stead.
The EMC experts are pretty clear on this issue: technology that blocks huge amounts of the HF-spectrum (which is already occupied by licenced services like amateur radio, shortwave broadcast, DRM, aironautical and maritime HF services) must be abandon.
